I was able to get some painting done yesterday, mostly small parts. It went pretty well and the Breathe-Cool supplied air system worked well. I recommend it to anyone painting with hardener.
I had some trouble with paint running on the battery box and starter. I think I was too close, trying to get at all the nooks and crannies. I was surprised at how thin the paint was and how hard to get in all the tight spots without running. I was using PPG Omni MTK with hardener and reducer in a 4-1-1 ratio.
My gun had a 1.4mm tip, I have a gauge at the gun and set it to 43# with the gun empty and full open. I cut back the fluid flow and varied the pattern from fan type pattern to a close to circle pattern on some small stuff. You can see some areas of primer on some of the pieces, mostly in seams and cracks
The recoat window per the spec sheet is 24 hours, raining here right now so I don’t know if I will be able try to get another coat before then. The way I understand it is after 24 hours I need to scuff or sand it before recoating, but I am not sure what grit or pad color to use.
Any tips would be appreciated. I do have a smaller gun with a .55mm tip as well as a small touch up gun with a .6mm tip.
You can see incomplete coverage at the bands around the starter and generator and runs on the starter
